Causes of puffy eyes include the aging process, water retention and allergies. Other causes include eye infections such as conjunctivitis or cellulitis. Since the causes of puffy eyes are so varied, it is important for sufferers to pay attention to their other symptoms — while swollen eyes and under-eye bags can often be treated with home remedies and lifestyle changes, some causes of puffy eyes require medical treatment. If an individual experiences puffy eyes that don't go away, or that are accompanied by other symptoms such as pain, bloodshot eyes or a discharge from the eye, they should see a doctor at once be properly diagnosed and treated.
In many cases, individuals find that skin under their eyes changes as they age. Both genetics and the thinning of skin over time can result in the appearance of eye bags which can be made worse if subcutaneous fat shifts to that area. If an individual is concerned about these changes, they can talk to their regular doctor and undergo an examination. If the problem is primarily cosmetic, the patient may want to ask for a referral to a plastic surgeon who may be able to improve the appearance of the patient's under-eye area.
It should be noted, however, that some of the causes of puffy eyes can be treated at home without resorting to surgery. For example, not getting a good night's sleep is one of the more common causes of puffy eyes and can be treated by adopting a healthy sleep schedule. Another possible reason for under eye swelling is the habit of sleeping on a completely flat surface, which can cause fluid to pool under the eyes during the night. Keeping the head elevated during sleep, by using pillows, cushions or an adjustable bed can go a long way toward treating the under eye bags. Another common home remedy for puffy eyes is the application of cold, wet tea bags which can help soothe the eye area.
Eye allergies and infections are other common causes of puffy eyes. In some cases, it is possible to treat eye allergies by using over-the-counter eyedrops formulated for allergy sufferers or by taking oral antihistamines. If the eye allergy does not respond to over-the-counter treatment, one should see a physician for professional diagnosis and treatment. Eye infections can also cause swelling around the eyes, and if an individual is frequently rubbing their eyes, this can make the appearance of puffy eyes worse. Once again, seeking medical attention for an eye infection can prevent the spread or worsening of the condition and any medications prescribed can alleviate the condition that is causing the eye area to swell.
